Someone braking their arm?

I don't know about accidentally, but with force you can break something! My oldest son punched one in high school and broke his hand straight across!

i really couldn't say if it could happen or not-to me you would think not because the force wouldn't be hard enough but then again its all in how you fall or how the arm bends when you trip so it could be possible

I've never heard a more embarrassing story! Well, maybe I have, but that sounds really bad. I don't think you need to take any precautions though, I don't think that happens very often! I don't know how someone could do that. Maybe they tripped or something, and they lost their balance, and the way they landed on their arm against the stall was really hard on their arm.

It could happen. If he hits his arm in the right spot, it can break. You can break a bone by doing the weirdest thing. So yes, it is possible.
